They keep sheets from getting greasy.
Size: 3 Pairs - Gray
These are good. I like that I can put lotion on my heels when I go to bed and not get my sheets greasy. They do a good job on that and a pretty good job keeping the moisturizer on. Since the toes are open, they aren’t hot.
The gel doesn’t seem to do anything, though.

Impressive
Size: 3 Pairs - Gray, Green, Pink
These socks are so cool and I have used them every night for a week and can see a difference. I am using them with the gold bond heel lotion.

Seem to help heal, but doesn't reach the balls of my feet
Size: 3 Pairs - Gray, Green, Pink
Only can wear when I am sitting down because they're to slippery to walk in

love these for soft feet!!
Size: 3 Pairs - Gray, Green, Pink
these are great. My feet are soft already! What I like best is my feet. Don't get hot in them because the heels and toes are exposed.
